Stainless Steel 321/ 321H/ 310/ 310S/ 314/ 317L/ 347/ 347H Shims
Introduction
Kalpataru piping is one of the leading manufacturer, suppliers, exporter of Stainless Steel 321/ 321H/ 310/ 314 Shims using high quality of raw material. Stainless Steel 321/ 321H/ 310/ 314 Shims have high strength and resistance to oxidation, carburisation and other harmful effects of high temperature exposure. The high contents of nickel and chromium in the alloys also give good corrosion resistance. Stainless Steel 321/ 321H/ 310/ 314 Shims was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, stainless steel 304l shims and 304H shims have superior creep and stress rupture properties. Stainless Steel 321/ 321H/ 310/ 314 Shims are used in a variety of applications involving exposure to corrosive environments and high temperatures such as heat treating equipment, chemical and petrochemical processing, nuclear power plants and the paper pulp industry. Heat-treating equipment such as baskets, trays, and fixtures employ stainless steel 304/304l/304h. Chemical and petrochemical processing industries use the alloys for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. Power plants use them for super-heater and re-heater tubing. We also offer these Products are available in different size,grades, specification & thickness as per the clients requirements.
